1 Version CVS HEAD (?)
3 * plugin changes:
4 - LV2 Persist + Files support (patch by David Robillard)
6 * packaging changes:
7 - fixed building with newer MinGW-w64
8 - Mac OS X: support the new dir for Core Audio SDK
9 - Mac OS X: fixed building outside source directory
10 - made sure all source files for hostplugins are included when
11 doing "make dist"
12 - removed empty directories left from the cvs to svn migration
13 - fixed compilation with gcc 4.6.1
14 - another "make dist" fix, for the LV2 plugin

16 - minor Makefile fix for building lscpparser when build and source
17 directories are separate
18 - Mac OS X: made it possible to specify plugin installation dir to
19 configure
20 - Mac OS X: Makefile fix for the install-strip target
22 * general changes:
23 - Refactoring: moved the independent code from
24 the Gigasampler format engine to base classes
25 - command line option '--profile' is currently disabled, since the
26 respective profiling code is currently broken
27 - Introduced support for optional environment variable

35 the 1st effect send of the sampler channel, no matter what the actual
36 effect type is)
37 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
38 note (in this implementation of the sampler its simply hard routed to
39 the 2nd effect send of the sampler channel, no matter what the actual

225 specified
227 * MIDI driver:
228 - ALSA MIDI driver supports now "NAME" device parameter, for overriding
229 the ALSA sequencer client name

273 * Bug fixes:
274 - Fixed crash which may occur when MIDI key + transpose is out of range
275 - minor valgrind fixes
276 - fixed crash which occurred when changing an already deployed sampler
277 channel to a different engine type
278 - fixed crash when deleting a sampler channel or changing engine
279 type while an instrument load was in progress
280 - bugfix: playing a note while changing the instrument could cause
281 a crash, or give "Handing back unknown region" error messages
282 - bugfix: calling SET VOICES (which Fantasia does on start and
283 refresh) could cause instruments to be unloaded
284 - Mac OS X: fixed name collision of enum in EffectControl and
285 wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
286 - Mac OS X: fixed hanging threads
287 - Windows: disabled the previous thread fix on non-Mac systems, as
288 it caused hanging threads on Windows
289 - Fixed possible crashes due to corrupted MIDI/audio device list
290 after MIDI/audio device creation failure
291 - When creating MIDI instrument map entries with "PERSISTENT" type, the
292 instruments were uselessly precached with zero samples, however it still
293 took the full preloading time and on 1st program change the respective
294 instrument was completely reloaded again.
295 - fixed handling of rapid bank select and program change messages
296 sent to the same sampler channel (patch from the Open Octave
297 project, slightly adjusted)
298 - fixed crash when trying to create an effect instance with controls
299 which min and/or max values depend on the sample rate
301 Version 1.0.0 (31 July 2009)
303 * packaging changes:
304 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
305 causing e.g. the libgig test to fail when
306 "./configure --disable-jack-driver" was used
307 (patch by Alexis Ballier)
308 - fixed compilation with gcc 4.3
309 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)

314 - minor fix in configure for mmsystem.h detection on MinGW
315 - Windows: look for editor plugins and Fantasia using base
316 directory of liblinuxsampler dll (look in the same directory and one
317 directory above)
318 - configure script fix: removed unconditional use of SSE
319 - fixed building with sqlite installed in a non-standard directory
320 - when cross-compiling, don't try to create instruments.db
321 - fix for new mingw-w64 version, which has usleep
323 * general changes:
324 - bugfix: on some POSIX systems instrument editor plugins refused to
325 load as we used a non-portable Linux specific struct field
326 (fixes bug #70, patch by Ronald Baljeu)
327 - fixed endless loop which occured when loading an instrument editor
328 plugin DLL on Windows systems failed
329 - fixed memory leaks that occurred when liblinuxsampler was unloaded
330 - optimized the SynchronizedConfig class so it doesn't wait
331 unnecessarily long after an update
332 - added support for notifying instrument editors on note-on / note-off
333 events (e.g. to highlight the pressed keys on the virtual keyboard
334 of gigedit)
335 - added support for triggering notes by instrument editors (see above)
336 - be verbose on DLL load errors (on Linux)
337 - fixed di-harmonic triangle LFO implementation (this LFO implementation
338 is only used by very few systems, most pick the int math
339 implementation, which is usually faster)
340 - fixes for audio drivers with varying buffer sizes
341 - experimental support for running LinuxSampler as a DSSI, LV2 and
342 VST plugin
343 - notification events for stream/voice count statistics are now sent
344 only when there are actual changes
345 - added memory ordering constraints to improve stability on
346 multi-core and multi-cpu systems
347 - maximum voices and disk streams can now be altered at runtime
348 - fixed CPU feature detection on x86_64 (maybe fixes #108)
349 - automatic stacktrace mechanism is now turned off by default and can
350 be switched on by command line option "--stacktrace" (the automatic
351 stacktrace mechanism seems to be broken on most systems at the moment)
352 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
353 a pointer to the launched InstrumentEditor object
354 - added optional 3rd party user data parameter for following
355 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
356 InstrumentEditor::Launch(),
357 InstrumentManager::LaunchInstrumentEditor()
358 - theoretical fix: made SynchronizedConfig follow C++0x memory
359 model more strictly
360 - fixes for using large audio device buffers
361 - Windows: add the installation directory to the DLL search path
362 when loading an editor plugin (solves problems with VST and
363 gigedit on systems with other GTK versions installed)
365 * audio driver:
366 - removed the nonsense audio channel constraint (which was hard coded to
367 max. 100 audio channels) for most audio drivers
368 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
369 opposed to the LSCP specs
370 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
371 reflected the wrong value
372 - fixed a memory management bug in ASIO driver
373 - Makefile fix: JACK_CFLAGS wasn't used
374 - JACK: use jack_client_open instead of the deprecated
375 jack_client_new
376 - added (experimental) CoreAudio driver
377 - applied old fixes to the ASIO driver that were included in the
378 previous binary release but accidentally never committed to CVS
379 (fixes #117)
380 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
381 win64)
382 - VST: added support for sample rate and buffer size changes
383 - VST: close editor (Fantasia) when the VST is removed
384 - VST: avoid opening Fantasia more than once for each VST instance
385 - VST: export main function as "main" on Linux too (fix for
386 energyXT)
387 - VST: changed number of output channels from one stereo to 16
388 stereo
389 - added channel routing, fxsends and midi maps to the settings
390 stored in the plugin state
391 - performance optimization of AudioChannel::MixTo() and
392 AudioChannel::CopyTo() methods using GCC vector exensions
393 (if available)
394 - ASIO fixes: avoid initializing the device twice, avoid throwing
395 exception when getting parameters from a disconnected device
397 * MIDI driver:
398 - added JACK MIDI driver
399 - dispatch bank select as ordinary CC as well, the user might seriously
400 want to (mis)use it for some purpose ("fixed" in all current MIDI
401 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
402 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
403 CoreMidi or AU
404 - fixed mingw-w64 compilation error in MME driver
405 - made program change handling in MIDI thread real-time safe by
406 moving the logic to a non-RT thread
407 - fixed minor memory leak in ALSA driver
409 * instruments database:
410 - avoid time consuming samples scanning when adding instruments
411 to the instruments database
412 - added support for handling lost files in the instruments database
413 - Implemented option for adding instruments in separate directories
414 in the instruments database
415 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
416 - work-around for missing fnmatch function on Windows to make
417 instrument database compilable
418 - added instrument database support on Windows
419 works with both standalone mode and VST plugin.
420 the instruments DB file is located in
421 %USERPROFILE%\.linuxsampler\instruments.db which allows different
422 databases for each windows user
423 if no DB is present it automatically creates the .linuxsampler subdir
424 and then creates an empty DB
425 - fixed recursive import, which was broken on Windows
427 * Gigasampler format engine:
428 - fixed a memory leak that could happen when a channel was deleted
429 while notes were playing
430 - made it possible to load an instrument even if the audio thread
431 isn't running
432 - added partial support for the "Controller Triggered" MIDI rule,
433 enough for piano gigs with pedal noise samples
434 - minor fix: only mark FX sends as being modified if really the
435 respective FX send MIDI controller was used
436 - added support for GM global device volume SysEx message
437 (can be selected at compile time to either apply globally to the
438 whole sampler [default] or only to the sampler channels that are
439 connected to the respective MIDI input port the SysEx message arrived
440 on)
441 - bugfix: notes triggered at position 0 in the audio buffer were
442 sometimes wrongly killed in the same buffer, causing no sound to
443 be played
444 - added support for chromatic / drumkit mode Roland GS Sysex message
445 which is usally used to switch a part between chromatic sounds and
446 drumkit sounds (as opposed to their common default setting of MIDI
447 part 10 being a drumkit part and all other ones chromatic parts), in
448 LS however one can switch between the first 16 MIDI instrument maps
449 defined for the sampler
450 - made it possible to create multiple sample channels even if the
451 audio thread isn't running
452 - fixed crash when removing channel with active voices (#116)
453 - bugfix: on sample reference changes (instrument editor), only
454 un-cache the respective sample if it's really not used by any
455 sampler engine anymore
456 - re-cache samples in case they were changed by an instrument editor,
457 e.g. when a sample was added while playing (#82)
458 - fixed hanging notes which occured when note-off event had the exact
459 same time stamp as the voice's note-on event and occured both in the
460 same audio fragment cycle (fixes bug #112)
461 - added support for the "fine tune" and "pitch bend range"
462 instrument-level gig parameters
463 - fixed minor artifacts in pitch bend handling
464 - added support for GS Reset SysEx message
465 - allow gig files to use unlimited downward pitch shifting
466 - added a limit check for upward pitch shifting
467 - bugfix: sometimes, when playing a note twice fast, the second
468 note was silent
469 - fixed crash happening when a pitch bend event arrived at the
470 same time a new instrument was loading
472 * LSCP server:
473 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
474 react on MIDI data arriving on certain sampler channels (so far only
475 Note-On and Note-Off events are sent via this LSCP event)
476 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
477 react on MIDI data arriving on certain MIDI input devices (so far only
478 Note-On and Note-Off events are sent via this LSCP event)
479 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
481 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
482 frontends to send MIDI messages to specific sampler channel
483 - added two additional fields to GET FILE INSTRUMENT INFO command -
485 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
486 was incorrect
487 - Optimized the retrieval of the MIDI instrument mappings
488 - added new LSCP command "SET VOICES" to globally alter the maximum
489 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
490 be triggered respectively
491 - added new LSCP command "SET STREAMS" to globally alter the maximum
492 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
493 which will be triggered respectively
494 - bugfix: retry if "select" returns EINTR (this fixes a crash when
495 a gigedit file dialog is opened)
496 - close all connections when LSCPServer is deleted
497 - hard close of all sockets on exit
498 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
499 driver
501 * Bug fixes:
502 - fixed a crash which occurs when removing a sampler channel waiting
503 to start instrument loading after another channel
504 - fixed a crash which occurs when removing a sampler channel with
505 instrument loading in progress (bug #113)
506 - fixed termination caused by uncaught exception when adding MIDI
507 instrument with PERSISTENT load mode
508 - fixed possible iterator invalidations when resetting the sampler
509 - fixed memory leaks when issuing the following LSCP commands:
514 - fixed possible compilation error when sqlite is not present
515 - fixed orphaned pointers when setting maximum voices limit (bug #118)
516 - fixed crash when changing the audio output device of a sampler
517 channel with loaded instrument and start playing notes
518 - fixed endless loop in Engine::SuspendAll() (bug #120)
519 - fixed a low-level atomic load function that was broken on 64-bit
520 PowerPC, which probably could cause crashes on that platform
521 - fixed a memory management error which could cause a crash when a
522 plugin was unloaded
523 - bugfix: two private structs had the same name, which could cause
524 problems if the linker chose the wrong constructor
525 - fixed low-level ConditionServer usage bug that caused lockups on
526 Windows
529 Version 0.5.1 (6 December 2007)
531 * packaging changes:
532 - added autoconf checks for pthread library
533 - added autoconf check for pthread bug found on certain NPTL-enabled
534 glibc versions (see Gentoo bug report #194076)
535 - added autoconf checks for MS Windows
537 * general changes:
538 - bugfix: the thread used by an editor plugin didn't die when the
539 editor closed
540 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
541 out all the space. operator--() did not apply size_mask after
542 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
543 order to avoid problems with the _NonVolatileReader functions.
544 - bugfix: Stream.h: added a missing divide by BytesPerSample in
545 GetWriteSpace(). Since this function is currently only used in
546 the stream's qsort() compare function, it didn't trigger any
547 bugs.
548 - Resampler.h, Synthesizer.h: cubic interpolation now works in
549 24bit mode too. Faster method to read 24bit words on little
550 endian machines (x86): replaced 3 byte reads + shifts with a 1
551 unaligned 32bit read and shift
552 - experimental support for MS Windows (MIDI input via MME, AUDIO
553 output via ASIO)
554 - made handling of SIGINT signal (Ctrl-C) a bit more robust
555 - support for monitoring the total number of active disk streams
556 (new LSCP commands: GET TOTAL_STREAM_COUNT,
559 * AUDIO driver:
560 - added Windows ASIO low latency audio driver
562 * MIDI driver:
563 - added MME Windows MIDI driver
565 * LSCP server:
566 - added support for Windows style path / filenames, however with
567 forward slash path separators instead of backslash
568 (i.e. "C:/foo/bar.gig")
569 - allow naughty liblscp to send non-string device parameters within
570 apostrophes as well
571 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
572 "LIST FILE INSTRUMENTS <file>" and
573 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
574 about an arbitrary instrument file on the system where the sampler is
575 running on
577 Version 0.5.0 (15 October 2007)
579 * packaging changes:
580 - config.h is not going to be installed along with liblinuxsampler's
581 API header files anymore
582 - only the API relevant header (and source) files will be exported to
583 the Doxygen API documentation (explicitly listed in Doxyfile.in)
584 - added completely new XCode project files for Mac OSX which is now
585 capable to execute our autoconf environment, thus no need anymore
586 to maintain the compile time configuration file (osx/version.h) for
587 OSX manually (patch by Toshi Nagata)
588 - fixed buggy boolean --enable-foo / --disable-foo configure script
589 parameters
590 - global.h now only covers global definitions that are needed for the
591 C++ API header files, all implementation internal global definitions
592 are now in global_private.h
593 - atomic.h is not exposed to the C++ API anymore
594 - no need to include config.h anymore for using LS's API header files
595 - fixed warnings in API doc generation
597 * general changes:
598 - replaced the old, confusing MIDI program change mechanism by a
599 flexible MIDI instrument mapper which allows to map arbitrary
600 (MIDI bank, MIDI program) pairs with arbitrary
601 (engine type, instrument file, file index) triplets which will be
602 loaded on the respective channel when such MIDI program change
603 messages arrive, beside that, each entry allows to define a life-time
604 strategy for the instrument, so the user can define whether the
605 instrument should i.e. be permanently loaded (to be able to switch
606 quickly among sounds) or i.e. loaded just on demand when the
607 respective program change arrives (to safe RAM space), as well as a
608 global volume factor for each entry, so the user can adjust the volume
609 dynamic of his mapped instrument collection without having to modify
610 the instrument files, also one can manage arbitrary amount of such
611 MIDI instrument maps and assign each sampler channel individually
612 a certain map, so that i.e. separation of normal instruments and
613 drumkits is possible
614 - new notification events for tracking changes to audio/MIDI devices,
615 MIDI instrument maps, MIDI instruments, FX sends, global volume.
616 - sampler was limited to load max. 200 instruments in the background
617 due to a constant size RingBuffer FIFO which is now replaced by a
618 dynamic (unlimited) size std::list FIFO
619 - added FX sends, these allow to route audio signals to arbitrary audio
620 output channels for being processed by external effect processors
621 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
622 controllers
623 - global (sampler wide) volume can now be controlled at runtime
624 - Implemented new, improved notification system
625 - fixed compilation errors regarding OSX
626 (patch by Toshi Nagata)
627 - implemented instruments database
628 - added support for escape sequences to the instruments database
629 - added highly experimental support for on-the-fly instrument editing
630 within the sampler's process (by using instrument editor plugins),
631 you'll notice the new "Registered instrument editors:" message on
632 startup, added a new LSCP command:
633 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
634 to spawn a matching instrument editor for the instrument on the
635 given sampler channel, the plugin path can be overridden at compile
636 time with ./configure --enable-plugin-dir=/some/dir
637 - added experimental code for synchronizing instrument editors hosted
638 in the sampler's process to safely edit instruments while playing
639 without a crash (hopefully) by either suspending single regions
640 wherever possible or if unavoidable whole engine(s)
641 - fixed several issues in fundamental "Thread" class: set scheduling
642 policy and priority on thread level, set a minimum stack size for
643 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
644 threads simply inherited properties of starting thread instead of
645 setting their own policy and priority
646 - minor fix in our automatic stack trace mechanism on crashes, the
647 main process did not wait for the stack trace process to finish
648 its output
649 - fixed some minor memory leaks
650 - reenabled assembly features support, at the moment only for
651 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
652 - minor assembly fix in x86 features detection (don't use the PIC
653 register, to avoid relocations in the text segment at runtime)
654 - POSIX callback functions of Thread.h are hidden
656 * MIDI driver:
657 - dispatch bank select (MSB and LSB) messages
659 * audio driver:
660 - the ALSA audio output driver parameters now reflect the correct
661 parameter value ranges for the respective selected sound card
662 (patch by Till Wimmer, a bit fixed and extended)
664 * Gigasampler format engine:
665 - if a filter is used and EG2 finishes before EG1, let the voice
666 die when EG2 has finished (this fixes a problem with clicks and
667 voice starvation for some gigs)
668 - playback is no longer disabled during instrument loading
669 - all notes playing on a channel that changes its instrument keep
670 playing with the old instrument until they get a note off
671 command
672 - EG fix: a release value of zero could cause noises or crash
673 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
674 - EG fine tuning: when attack is zero the EG starts at a level
675 above max sustain level, which means that there is a decay phase
676 even if sustain is 100%
677 - more EG fixes: the level could sometimes go below zero and cause
678 noises or crashes
679 - minor fix of EGDecay (patch by Toshi Nagata)
680 - fixed compiler error when --enable-override-filter-type was
681 supplied to the configure script (fixes #46)
682 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
683 instead of a fix value
684 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
685 127 (solo mode) only kill voices if the respective mode really
686 changed
688 * LSCP server:
689 - fixed compile time error for old Bison versions
690 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
691 - parser now supports extended ASCII character set
692 (up to ASCII code 255, i.e. includes now umlauts and accents)
693 - filename arguments in LSCP commands now allow to use escape
694 sequences, that is directly literal as one of: \', \", \\, \n, \r,
695 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
696 code value like \xf2) (fixes bug #24)
697 - the following LSCP commands now also support escape sequences for at
698 least one of their text-based parameters (i.e. name, description):
705 - returns verbose syntax errors (line and column where syntax error
706 occured, the unexpected character and the actually expected, possible
707 character(s), the latter only if less than 5 possibilities)
708 - made sure that LSCP syntax is not affected by gigedit locale
709 settings
710 - bugfix regarding strings parameter lists: all comma separated lists
711 of strings were treated as being one string containing commas
712 (fixes #57)
714 * Bug fixes:
715 - fixed crash occurring on certain LSCP scripts (Bug 39)
716 - another thread safety fix for lscp "load engine" and "set
717 channel audio output device"
718 - fixed a crash which occurs when reassigning the same engine
719 on a sampler channel with connected MIDI device
720 - fixed a crash which occurs when changing the number of ports of a MIDI
721 device connected to a sampler channel to number less then or equal
722 to the index of the port to which the sampler channel is connected.
723 - The previous bindings were not been disconnected when altering
724 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
725 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
726 - The active stream/voice count statistic was incorrect.
727 - notification events were not been sent for some sampler
728 channel changes
729 - added default min and max values to restrict the number of allowed
730 audio output channels and MIDI input ports
731 - the connection to the PCM interface is now closed when destroying
732 an audio output device
733 - files with slash in their path or filename could not be loaded
735 * test cases:
736 - updated and fixed (haven't been touched in a while)
738 Version 0.4.0 (24 November 2006)
740 * packaging changes:
741 - changed deprecated copyright attribute to license; added ldconfig
742 to post-(un)install steps; added devel package for liblinuxsampler;
743 to linuxsampler.spec (RPM)
744 - install necessary development header files for allowing 3rd party
745 applications to link against liblinuxsampler
746 - liblinuxsampler's API documentation can be generated with 'make docs'
747 (Doxygen required)
748 - added benchmark to automatically detect the best triangle LFO
749 implementation (currently either an integer math solution or a
750 di-harmonic approximation), automatic detection can be overriden
751 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
752 configure script argument though (mandatory for cross-compilation)
753 - do not automatically pick optimized gcc flags if the user already
754 provided some on his own (as CXXFLAGS)
755 - added compile time option to disable processing of All-Notes-Off MIDI
756 messages
757 - added compile time options to allow disabling the various audio and
758 MIDI drivers
759 - fixed automatic GCC CPU switch detection on PPC
760 (patch by Ebrahim Mayat)
762 * Gigasampler format engine:
763 - extensive synthesis optimization
764 (reimplementation of EGs and LFO(s), removed synthesis parameter
765 prerendering and the synthesis parameter matrix in general, splitting
766 each audio fragment into subfragments now where each subfragment uses
767 constant pitch and filter coefficients. The volume coefficient is
768 linearly interpolated inside a subfragment, unless
769 --disable-interpolate-volume is set.)
770 - fine tuning of the EG modulation parameters
771 - improved filter cutoff calculation by adding support for the
772 following gig parameters: Cutoff freq (used when no cutoff
773 controller is defined), Control invert, Minimum cutoff, Velocity
774 curve and Velocity range. The keyboard tracking now scales
775 cutoff frequency instead of resonance.
776 - added support for gig parameter Resonance.
777 - fixed bug in sysex handling (patch by Juan Linietsky)
778 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
779 which can be overridden with --enable-global-attenuation
780 - EG fixes: made the length of "attack hold" stage more
781 accurate. Release stage can now start before attack stage
782 ends. Cancel release didn't work when sustain was zero. Attack
783 time now has a minimal value to prevent clicks.
784 - fixed pitch changes larger than one octave
785 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
786 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
787 all modes can be altered via standard GM messages, that is CC5 for
788 altering portamento time, CC65 for enabling / disabling portamento
789 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
790 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
791 parameter) and crossfade
792 - added support for the "attenuation controller threshold" gig
793 parameter
794 - added smoothing of volume changes caused by control change
795 messages
796 - sample loop parameters are now taken from the DimensionRegion
797 instead of the wave chunk
798 - fixed keyswitching for v3 gigs with a number of keyswitch splits
799 not equal to a power of two
800 - reimplementation of the filter algorithm. The new filter is more
801 accurate and supports all gig filter types, including bandreject
802 and lowpass turbo.
803 - real support for 24 bit samples - samples are not truncated to
804 16 bits anymore
805 - support for aftertouch (channel pressure, not polyphonic
806 aftertouch)
807 - LFO1 behaviour fixed (dampening from max volume instead of
808 amplifying from 0)
810 * LSCP server:
811 - fixed application exit on broken pipe error (fixes bug #20)
812 - fixed the notification messages delay due to lack of
813 network activity (fixes bug #26)
814 - fixed parser bug which occured on space(s) within device parameters
817 * audio driver:
818 - added aRts audio output driver (by no means RT safe)
820 * MIDI driver:
821 - fixed legacy sysex code which caused dispatching of MIDI SysEx
822 messages several times instead of once
823 - API extension for MIDI drivers which already supply exact time stamps
824 for events (i.e. for offline rendering based MIDI drivers)
825 - added checks for bad MIDI data
827 * linuxsampler application:
828 - show available sampler engine types on startup
830 * general changes:
831 - support for muting sampler channels and solo mode of the same, two new
832 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
833 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
834 introduced for this, the behavior is the same like on a mixer console
835 (patch by Grigor Iliev, a bit adjusted). Also added configure option
836 --enable-process-muted-channels which can be used to enable the
837 processing of muted channels.
838 - support for sostenuto pedal
839 - support for monitoring the total number of active voices
842 - fixed some memory management errors
843 - fixed some concurrency problems that could lead to crashes when
844 LSCP commands were executed
845 - fixed crash when instrument loading failed previously on the same
846 sampler channel (fixes bug #36)
848 Version 0.3.3 (15 July 2005)
850 * packaging changes:
851 - fixed compilation with gcc 4.0
853 * Gigasampler format engine:
854 - LFO preprocessing was performed even though the respective LFO was
855 disabled by the instrument patch (minor efficiency fix)
856 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
857 for volume ramp downs in the same fragment (needed for current voice
858 stealing implementation) then simply inform the user with a warning
859 about possible click sounds and reduce the volume ramp down
860 appropriately instead of cancelling the audio device connection
862 Version 0.3.2 (24 June 2005)
864 * packaging changes:
865 - updated autotools build files to compile on OS X
866 (conditional compilation of CoreMIDI and MidiShare drivers)
867 - hand-crafted assembly optimization code can be disabled with
868 './configure --disable-asm' (definitely not recommended)
869 - fixed 'make dist' rule to include all necessary files
870 - require automake (>= 1.5) for 'make -f Makefile.cvs'
871 (due to 'dist-bzip2' automake option)
873 * Gigasampler format engine:
874 - support for the gig parameters for "release velocity response" curves
875 - fine tuning of the EGADSR envelope
876 - volume of release triggered samples now depends on note-on velocity,
877 note length and gig parameter "release trigger decay" instead of
878 note-off velocity.
879 - revised voice stealing
880 (fixes crash and endless loop caused by voice stealing)
881 - don't reset scale tuning on instrument or audio output device change
882 - handle key group conflicts right at the beginning of each fragment
883 instead of when the respective voice is actually launched
884 (fixes undefined behavior if stolen voices belonged to a key group -
885 this case was followed by a "killed voice survived" error message)
886 - fixed minor issue with null/silence samples
887 (those stole voices even though they don't need a voice at all which
888 resulted in "voice stealing didn't work out" messages)
889 - don't reset volume, pan, pitch and MIDI controller values on
890 instrument or audio output device change
892 * LSCP server:
893 - fixed some crashes (patch by Grigor Iliev, fixes #19)
894 - fixed LSCP event "CHANNEL_INFO" notification
895 (e.g. did not notify on volume changes or MIDI program change events)
897 * linuxsampler application:
898 - added command line parameters --lscp-addr and --lscp-port to override
899 default IP address and port of LSCP server
901 Version 0.3.1 (24 May 2005)
903 * initial release
